r es DEVICE FOR FLUSI-IING DRAIN PIPES Application filed November 30,1929. Serial No. 410,805.

My invention relates to improvements in devices for flushing drain pipes, and one object of my invention is the provision of a device which can be instantly applied to the faucet of a sink, bath tub, or like structure and which will thoroughly and quickly by the force of the water clean the drain pipe and remove any obstruction therefrom.

Another object of my invention is the provision of a device which can be uickly attached to a threaded or smooth taucet and which will utilize the full force of the water to remove any accumulation or stoppage in the drain pipe.

Another and most important object of my invention is the provision of a device of the character and for the purposes stated which will prove eflicient and practical in use and which can be made at such a small price as so to render the device an absolute necessity in s with a strainer the household.

With these objects in view my invention consists of a drain pipe flushing device embodying novel features of construction and arrangement of parts, substantially as described and claimed, and as shown in the accompanying drawings, in which:

Figure 1 represents a side elevation of my complete device shown in connection with a faucet and drain pipe to demonstrate the manner of using my device.

Figure 2 represents a sectional view of the nozzle used in this form of my device.

Figure 3 represents a view in side elevar tion of a modified form of my invention such as used in flushing a drain pipe having a strainer, the strainer and cup of my device being shown in section, and

Figure 4 represents a sectional view of the novel faucet coupling of my invention.

My invention is particularly adapted for use in connection with a faucet 1, for flushing the drain pipe 2, of a sink 3, which may be of the open type 4, or may be provided 5, the device 0 crating in connection with either constructlon.

The invention according to my improvements is of the most simple and inexpensive construction and as shown in Figures 1 and 2, consists of the faucet coupling sleeve 6,

. when the jambing or the flexible pipe or tube 7 and the nozzle 8,

which fits after the manner 01": a plug in the drain pipe outlet 9.

The modified form of my invention shown in Figures 3 and 4; and

for use in connection with either a which is adapted smooth faucet or one provided with threads, em-

ploys the novel coupling which consists of tapered sleeve 10, having interior threads 11 and exterior the threaded to clamp the sleeve being formed with low the sleeve to be adjusting co threads 12, which latter on the tapered portion of the sleeve are engaged by llar 13, which acts sleeve 10 on the faucet, said slots 11 which alclamped on the faucet adjusting collar 13 is rotated, and said collar is retained in proper relation to the tapered sleeve by means of the annular band 14:, 15, which fits in an formed with a flange annular groove 15 of said collar 13, and this form of my invention is provided at the other end of the tube or pipe 7, with a hook 16, to engage the strainer and hold the pipe in position and with a cup 17 which fits over the strainer.

The manner of using my device is so readily apparent from the drawing and descripthe drain pipe of the sink or bath that the device can be produced low price as to make it a h I claim:

tub and at such a ousehold necessity.

l. A device for flushing drain pipes, comprising a tube having a coupling for connection with a faucet, said coupling consist- 1ng of a tapered sleeve having a series of vertical slots and interior threads,

and exterior screw an adjusting threaded collar for enthe exterior threads of said sleeve and having an annular groove in its outer one end connected face, and a band having to said tube and the other end formed with A a flange at its upper edge to engage the annular groove of said band of said collar to guide and retain said col 2. A flushing device of for the purpose describe lar.

the character and d, consisting of a:

sleeve having interior screw threads and a series of vertical slots and having an outer tapered threaded Wall a collar having tapered opening formed With threads to engage the threads of said sleeve to form a clamp upon said sleeve and said collar being formed with an annular groove, a band having a threaded portion at its lower end for connection with a flushing pipe and hav- 10 ing a flange at its upper end to engage the groove of said collar.

In testimony whereof I afiix my signature.
